Even studs dig into sheet ice if you were to slide sideways. True they''re harder on the road surface, but a person needs all the control they can get, including the non powered, non steerable, wheel.
I still see the same problems today. People put the best, or weather based, tires on the powered end, while ignoring the wheels that are drug, or pushed, through the same weather.
Common sense, "if" a person has trouble starting to move in snow and ice, they put better tires on the powered set of wheels, "BUT" you've ignored the fact, the non powered wheels have just as much trouble gripping as well! On a rear wheel drive vehicle, you end up with stopping and steering issues from the "less" tires you didn't replace.
Front wheel drive has the advantage on slippery surfaces, but I'll take the additional grip on the rear as well. I won't have a contest on who drove in worse conditions. I've got a lot of miles behind me though, in all conditions, including black ice and high winds.
How many times a year are you driving on sheet ice?
I can see having studs if you live in the mountains (not hills, real mountains like the Rockies or the Cascades)
Studs are not the best choice in a lot of typical winter conditions. You also have to compare how often the needed situation compare to daily driving.
Studs on dry pavement are not a good driving situation when it comes to stopping and handling.

"So which is better, studded tires or winter tires? It depends. According to Pemco Insurance, studies show that studded tires perform best on clear ice in temperatures around the freezing mark, while winter tires deliver the best handling and braking when the temperature is below freezing, on both wet and dry pavement.1
If you think you’d like to try out a set of studded tires, there are a few other things to take into consideration, number one being where you live. Metals studs are prohibited in 11 states -- Alabama, Florida, Hawaii, Illinois, Louisiana, Maryland, Michigan, Minnesota, Mississippi, Texas, and Wisconsin (some of these states allow tires with rubber studs; Maryland allows studs only in certain counties). Only six states permit the use of studded tires without restriction: Colorado, Kentucky, New Hampshire, New Mexico, Vermont, and Wyoming. Most of the remaining states allow studded tires with date restrictions. For example, in Washington State where the TireBuyer offices are located, studded tires are permitted from November 1 – March 31. If you decide to use studded tires, be sure to follow your state’s law or risk paying a hefty fine. See the chart below for detailed studded tire laws for each state."
